Patsy, perhaps the most recognized of EFFanBEE's dolls, defined the company from 1920-1950. Master doll modeler Bernard Lipfert designed this 1947 Patsy, still in her original costume but missing the identifying gold heart-shaped tag. Unlike the first models, which had cloth bodies, this Patsy is entirely composition, a mixture of wood pulp and glue. In the early 20th century, increased leisure time and changing social demands led to changes in the way children played. Play changed from practical training in etiquette and such domestic crafts as sewing to the acting out of personal relationships. Dolls became companions, not objects for instruction. As home sewing declined after World War I, doll manufacturers emphasized doll accessories and companions. With her extensive wardrobe, boyfriend, and six siblings, Patsy revolutionized the industry and served as the forerunner of Barbie. Patsy remained popular through the Great Depression, even as more-expensive dolls fell out of favor. Interrupted for a few years by World War II, production of Patsy dolls continued until 1950.
